Active fingerprinting combines digital media watermarking and codes for collusion-secure customer identification. This requires specialized strategies for watermark embedding to lessen the thread of attacks like marked media comparison or mixing. We introduce basic technologies for fingerprinting and digital watermarking and possible attacks against active fingerprinting. Based on this, we provide test results, discuss the consequences and suggest an optimized embedding method for audio fingerprinting.
